Upon further investigation — and actually asking E.L.F. Cosmetics what the deal is with the secret product compartment on their lipsticks — Allure discovered that this isn't an accompanying lip balm, but an extra bit of the same lipstick. E.L.F. told Allure, "We know the best way to color match is to see the actual product, so we designed our moisturizing lipsticks to hold the lipstick formula. This feature makes it easier to color match — and we love that it’s been a surprise and delight for many of our fans."

While the sample idea is pretty genius — and helps us stay away from the (usually) nasty as hell testers we find in drug stores — the extra product will also come in handy when you own the E.L.F. moisturizing lipsticks too. Run out of your favorite lippy and not had time to pick up a new one? Pop open that little secret compartment and go wild. The party don't stop til, well, that little compartment runs out too. But when it does? Another one of these moisturizing lipsticks will only set you back $3. Talk about getting more for your money!

Available in 17 shades ranging from gorgeous neutrals, deep purples and brighter tones too, these lipsticks are a perfect addition to any makeup bag. Cheap, pretty, and with an added bonus party trick — what more do you want from a cosmetic?
